What are drought conditions?
A drought is defined as “a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious hydrologic imbalance in the affected area.” -Glossary of Meteorology (1959). Hydrological-occurs when surface and subsurface water supplies are below normal.
What does a drought mean?
To a meteorologist, a drought is a prolonged period when precipitation is less than normal. To a water manager, a drought is a deficiency in water supply that affects water availability and water quality. To a hydrologist, a drought is an extended period of decreased precipitation and streamflow.
How is drought caused?
The Short Answer: A drought is caused by drier than normal conditions that can eventually lead to water supply problems. Really hot temperatures can make a drought worse by evaporating moisture from the soil. But droughts don’t just happen in hot and dry places.
What is drought in simple words?
A drought is a long period with no rain or unusually low levels of rain or other precipitation. Because weather and climate are different in different places throughout the world, there is no single definition of what counts as a drought.

Can drought be caused by humans?
Human activity can directly trigger exacerbating factors such as over farming, excessive irrigation, deforestation, and erosion adversely impact the ability of the land to capture and hold water.
How do droughts impact on human activities?
Drought can also affect people’s health and safety. Examples of drought impacts on society include anxiety or depression about economic losses, conflicts when there is not enough water, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and even loss of human life.
What are human impacts on drought?
In a recent article, we call this anthropogenic drought, which is water stress caused or intensified by human activities, including increased demand, outdated water management, climate change from anthropogenic greenhouse gas emissions, growing energy and food production, intensive irrigation, diminished supplies, and …
What are the effects of drought on water resources?
A 1-year drought not only causes water level decreases, but also results in many other changes. When water levels decrease, solutes become more concentrated as the amounts of water decrease in rivers.
What are effects of drought on environment?
| Examples of Environmental Impacts of Drought | |
|---|---|
| Fish and Animals | Reduction and degradation of fish and wildlife habitat. Lack of drinking water for livestock and wildlife. |
| Water Sources | Lower water levels in reservoirs, lakes, and ponds. Reduced streamflow. |
| Land | Reduced soil quality. Increased quantity of dust. |
